Maybe the Bravos would have stayed on the transom if the gear lube was mixed with toluene and cider vinegar.

It's been a while since I've been on their website but Sonny's does advertise a 711 cubic inch big block Chevy with a PSI supercharger making either 1400 or 1600 horsepower on pump gas specifically for marine use.
if I remember correctly at the time they sell for $113,000 each.

Never seen a boat with them though.
